gorilla middleware

https://github.com/pink-gorilla/gorilla-middleware [org.pinkgorilla/gorilla-middleware "0.2.1"]

• uses [nrepl "0.6.0"] and [cider/cider-nrepl "0.22.4"]
• NRepl defines the nrepl messenging protocol
• cider extends operations to the nrepl protocol (example: interruptable eval) https://github.com/pink-gorilla/gorilla-notebook/blob/master/src/clj/gorilla_repl/nrepl.clj

gorilla notebook

• runs the repl server in https://github.com/pink-gorilla/gorilla-notebook/blob/master/src/clj/gorilla_repl/nrepl.clj
• the reagent app consumes a websocket that runs the nrepl messenging protocol
